Y Swppm'tng and driving connections a The general construction of the machine' is similar to that of the well-known Banner machine as shown in the patent `to Hemphill, No.9333443, September 7, 1909, said construction including a revolving needle cylinder and a stationary sup rt 26 on .which are mounted a slidin bloc 27 ca cams for the cylinder ne les 27 (FigfAi tie pickers of whichI one is indicated at 28, the instep I cams 29, and various other partsof the mech- .anism.

A bracket 30 vis mounted on the sup rt 26 said bracket extending over the cylin er an rovided at its outer end with an aperture t rough which passes thedial 32. A gear 33 1s secured to the ,sinker bed outside of and just below the sinker cam ring 25. A similar gear 34. is secured to the upper end of the dial post by means of a nut 35 said gear resting on a flange 36 of the post which flange rests on the bracket 30. As shown in Fig.'3 the web of the gear is cut out-toA reduce its wei ht7 or it ma be solid if referredf. A 'sha 37 (Fig. 2l is journal in supported by the bracket 30 and said sha 38 and 39 the teeth of which l mesh respectively with lthe teeth of 34 c with the needle- .lindernv Thesl .'is mounted to rotatgyin a sleeve 40@ poi-ted at the end of thebracket 30. A late `and 33 thus drivingl the dial in '41 is preferably formed in one piece wi the Il i o open the sleeve said plate having a cam slot in which a follower 42 (Fig. 18) is movably mounted. The late 41 is here shown as being approximate 4y3 on a level with the top ofthe latch e dial 44 is secured to the lower end of the dial in any convenient manner. Above the 'al is a dial cam cap 45 shown in detail in Figures 13 to 16 and above this is a plate 1 46, preferably annular, which is substantially stationary but may have a slight oscillatory movement, the extent of which is determined by means of a set screw 47 engaging the pin 48 on the plate 46 extending. upward through 15 a slot inthe plate 41 (Fig. 3). Prefcrablf a lost motion connection is-provided between the plate and the plate41 as this is yfound to prevent cramplng of the parts on vthe plate and their connections. i

The cylinder is driven as usual by a gear 49 on a shaft driven from a belt` 50 through a set of pulleys 51,52, 53, gearing 54 being inte as usual for causing th gear 49 and e needle cylinder to rotate m oscillate in well-known manner. In 1.1;; invention obviously the dial will have m-.wcments similar to those of the cylinder.

Dial and controlling metil-:adem therefor At its underside the dial cam cap is*y provided with an outer wall or rib 55 (Fig. 13) combining in itself guard cams and needle retracting cams 57 and 58. The knockingr u over point of the needle retractingeportion is at 56. The outer wall of the n le-butt ^path is interrupted at one point by a gap closed by -a gate 59 which gate is slidable in a counterclockwise direction in Figure 17 to p and rmit the removal of the dial needles 59' 1g. 13). 'A spring 60 serves to return the gate to closed position. The inner wall of the needle butt path is formed by a downward projection 61 of the cam cap a which projection is reduced at one side to provide space for an oscillatorv needle projecting cam 62 pivoted at 63. The oscillation'of the cam is brought about by movement of the dial cam cap about the dial post as an 'axis 5 whereupon the needle projecting cam is moved in and out by the cam path in the late 41 in which path the follower 42 travels. e cam cap has an upwardly projecting circular portion 64 (Fig. 2) which engages 5 the inner periphery ofthe plate 46 and aids in holding the parts in place.

The oscillation of the cam cap for adjusting the needle propecting cam toits various positions is effected by a train of mechanism n including link 65 pivotally connected to the dial cam' and to a rod 66 slidably supported ina bearing 67 mounted at one side of the bracket 30. The bearing has a lateral extension 68 with a slot at one side in 5 which is guided a pin 69 extending into a slot in a rockarm 70 (Figs. 1 and 3). The rockarm is fixed to a rockshaft 71 journaled in a sleeve 72. The rockshaft at its other end is provided with a Vgear 7 3 having a set of teeth,

(Fig. 5) arranged for actuation by lugs on a attern chain 78 positioned to engage with a aterally extending pin 79 at the free end of the lever.

The pattern chain passes over an independly rotatable l sprocket 80 which sprocket is driven by a ratchet 81. A pawl 82 is mounted as usual on the oscillating quadrant which causes the machine to knit reciprocatingly and said pawl normally moves the ratchet one step for four rotations of the needle cylinder. At certain times a higher speed is desirable, such as one step for each revolution of the needle cylinder.

I have provided means for speeding up the movement of the chain at certain times. which means. however. cannot be used throughout the knitting of the entire stocking as it would interfere with the proper operation of the machine in knitting heels and toes, and a verv long chain would be required.

For the purpose of speeding up the movement ofthe chain at certain times another pawl indicated at 83 is-arranged for engagement with the ratchet, this pawl being constantly operated by an eccentric 84 on which the pawl is pivotally supported. The eccentric is driven by a gear 85 with which it may be integral which gear is driven fronra series of gears 86,V 87, 88, the latter being the quadrant driving gear of the Banner knitting machine. Y

The pawl 83 is normally held out of action by gravity and an elevator 89 engages the underside of the pawl for lifting it intoengagement wit-h the ratchet, the elevator being pivotally mounted and pressed upward by a spring 90. When this is done the ratchet will be driven a step for each rotation of the needle cylinder, the pawl being moved at this rate by the'l gearing indicated. The elevator 89 is moved downward on its pivot 90 by an eccentric portion 93 of a shaft 92 shown in detail in Figures 7 and 8. The 'shaft has another eccentric portion at 91 passing through a slot in a lever 94 pivoted at 95 (Fig. 5). At its forward end the lever is connected by a. pin and slot connection to a vertically slidable rod 96 (Figs. 5 and 5a) provided at its upper end with a finger 96 acted on by a spring 97 said finger engaging the underside of the pawl 82. The purpose of this yielding action of spring 97 is to prevent damage to the meenam should the rod. 96 be ,lifted while the pawl is being moved forward and. is

. pressingagainst a ratchet tooth in which case the iin r can yield'until the pawl is released from e ratchet whereupon the pawl will be lifted.

The shaft 92 is journaled in a. supportl screw 98'. A pawl100 (Fig. 9) is pivoted in a circumferential notch on the ratchet drum said pawl being impelled by a spring 101 a directionto engage with notches at 102 1li the sleeve portion 4of the gear 97. A leaf spring 103has a bent end for engagement in notches in the ratchet drum for holding it in place after it has been driven through ahalf rotation by the shaft 92 acting through the ratchet clutch.

The rack segment 99 (Fig. 6) is pivoted on a lixed support and is connected by a. link 104 to a lever 105, pivoted at 106, and carrying Aa pin at 107 engaging a slot' in a lever 108.

The levei' 108 is positioned for engagement at its free end by a lug 109 on the chain 78. A spring 110 serves to hold the lever normally in the position of Fi re 6.

' In 'the operation o the chain driving means the parts are normally in the opposite position to that indicated in Figure 5 with the pawl 82 engaging the ratchet 81 and'drivg thechalnlom-,step to four rotations of the Il needle cylinde 1,n ddial., When it becomes desirahlefi'tno s eed theloperation of the P` n n chain, as during the transfer from plain to Ihis brings the .eccentrics 91 and 93 into ,thel positionshojwn in Figures 5', 6' and .8. 'The' rib knitting, in'casting off or in 'making a welt a lug 109 on the lchain engages the adjacent end of the lever 108. The surface at the upper side of the short portion of the curved slot in said lever now` bears down on the pin 107 of the lever 105 and by the movement of this lever about its pivot 106 acts through the link 104 and quadrant 99 to turn thegear 97 and rotate the shaft 92 through anarc of 180".

eccentric 91; acts on lever ,-94 to lift the` rod 96 andp'awl 8 2 position-shown in Figure 5..

At the same ti n u'a. thev eccentric portion '93 has been moved upward to relieve its pressure on the elevator 8 9 which'visjnow moved upwardby its spring 90 andcarries the pawl 83 into engagementl with `'theratchet whereupon the ratchet l81, sprocket-1801 andi'chain are moved' one step for- Teach revolution of ythe .o needle cylinder'` and dial. j Ths-action "con" tinues until the lug`109 on` the chain passes the free endof leven-e108 whereupon the o eration just described is'reversedand .t e gauw! 82 is returned to action. When the pawlk returns to action Vthe chain is again-movedthe s afthy means of the ratchet clutch.

A locking or latching device is provided for holding thev dial cam cap in. a position which correspondsto -the idle position of the dial needle cam 62 (Figs. 2 and 3). This locking means comprises a rocker 111 havin a triangular lug 112 at one side thereof.

`fixed abutment 113 of approximately elliphis lug is adapted to engage in a notch at 113 on a tical shape having both -ends pointed. Such engagement occurs on movement of the rocklarm 0 to the left in Figure 2 by-a lug on the pattern chain 7 8 through levers and connections between the'said chain 78 and a rock arm 70. To release the latch it is moved further to the left as by a. higher lug on chain 78 and descends under the influence of gravity plus 'the (action of the cam at 113" below the level of abutment 113 wh ereupon the lug 112 strikes the upper surface of a lever 114 piv oted at-115 and supported in the position indicated by a coil spring115 connected at one end to a pin 116-on the lever which pin extends through a slot in the rearmost one of a pair of plates 117 between which the rocker v 111 and lever-114 are guided for up and down movement. At its upper end the spring is attached to a suitable holdin means at the farther side of the rear one o the plates 117.

Itwill be seen that the lever 114: will support the lug 112 which when the rockarm 70 f moves to the right will ride underneath the los over the abutment 113. When the locking means is released the rod 66l will be moved to the right in Figure 2 by a-spring 118 to the limitof itsv movement in that direction.

When the cam follower 42 reaches vthe end tera, Figure 18,'the. dial cam is inthe locked position and is thereby prevented from being tions, i. e., whenl ajpattern chaining .is ot operative the latchserves the purpose'intended.

The cams for-iv'perating needles4 are shownjin detail 1n Figure4 and comprisea bottom center cam 119, a top cenof the cam slot indicated Vby the'reference letun ter cam 120, stitch 'camsg121 and 122, a needle raising cam 123 anda the same. The top an .bottom center cams vandthe stitch cams shown at the right in Figard cam 124 above ure 4 may be as in the prior art but stitch cam 122 has an extended horizontal portion at 125 for holding down the cylinder needles until the dial needles have drawn their loops. The needle raising cam 126 is, of course, similarly formed, so as to provide a narrow path for the needle butts.

The machine of my invention is provided with sinkers whereas the ordinary ribber does not have sinkers. By reason of the presence of the sinkers the fabric cannot pass down to the take-up in the same direct manner from m machine as is the case in conventional ri bers. Cam 123 is therefore provided for lifting the needles to a greater height: than would be necessary in plain knitting or even in a conventional ribber. It will be understood that the level of the verge of the 'formingfabric is raised during' rib knit-` ting since while knitting plain fabric the position of this verge is determined by the sinkers or in other wordsy the work isV held by the throats of the sinkers whereas in rib knitting the dial needles necearily pull the fabric upward to a certain extent, away from the throats of the sinkers.

It is important also that the needles be not so high during reciprocating knitting when the cylinder needles alone are in operation as to fail to engage the pickers, or as to engage at improper times and dama the machine. The cam 124 lnds its usefulness during the reciprocating part of plain knitting when the low lace at the left-hand side in Figure 4 can ring the needles down to prevent their butts from striking the droppers while the up-picks are acting to narrow the. fabric and locate the butts roperly for engagement -by said 11p-picks. and narrowing vof the fabric the low part of the cam 124 at the right-hand side in Figure 4 finds its useful function in that it brin the needle butts to the proper level for t e action of the u picks. For this reason the guard cam 124 1s provided with low parts at each side of the cam 123 so as to bring the needles down immediately to an elevation at which the pickers can act to move the needlesin widening and narrowing.

` Stitchrlength control The'main cam shaft 127 is driven by a pawl engaging a coarse ratchet 128. The rotation ofV the shaft controls in the usual manner changes in speed by means of a cam 129 acting ring the above widening.

der. For a sharp control over the length of stitches to enable such length to be changed, e. g. in successive revolutions, the cam shaft is provided with a ratchet disk 135 (Fig. 1

having a short series of closely spaced teet at 136 (Figs. 1 and 5) these teeth being ositioned for engagement by a pawl 137 w ich may be mounted on the sameeccentric 84 as the pawl 83 or on a similarly located eccentric. The pawl 137 is always in engagement with the periphery of the disk 1 35 so that when the teeth 136 come into position to be engaged the cam shaft has moved one ste for each rotation of the needle cylinder. This arrangement may be utilized for ehangin the length of stitches quickly as is desirabe in transferring from plain to rib knitting. In

, the present instance the teeth are positioned to operate the cam shaftrapidlyfor changing the length of the stitch at the time of transfer from plain tio rib knitting.

Yam feeding vThe machine is provided with the usual yarn fingers 138 operated from the pattern mechanism by means of levers 139, links 140 and levers 141 resting on the cams 131. The ring 46 (Fig. 18) is provided with a resilient yarn clamp 142, a hook 143 underneath which the yarn passes, and a shear having a stationary blade 144 and a movable blade 1.45. The shear is operated by a plunger 146 (Fig. 19) here shown as provided with a roller at the top for engagement with a cam 147 (Fi 19) at the underside ,of the gear 34. A lin 148 connects the plunger to the movable shear blade. lA yarn pusher 149 is pivotally supported on the bracket 30 and is moved in onel direction by a cam 151 on the pr 34 against the tension of a spring 151. e pusher has a notch at its forward end for engagement' with. a yarn that is moved into idle position and it is moved by a cam 151 in a manner to pick up an intermediate part of a yarn extending from an idle yarn-finger about the edge of the dial to the knitted fabric and to carry such a yarn into a position underneath the clamp 142 and into the space between the shear blades, as illustrated in Fig. 18. It will be understoodthat when the cam 151 releases the pusher it will move toward the back of the machine suiciently far to pick up the next yarn moved up out of knitting position. The pusher swings back and forth at. each rotation of the machine, but acts only on idle yarns. as the yarn which is being fed tothe needles lies below the path of the pusher.

Take-up mechanism The take-up mechanism (Figs. 1. 10 and 11) for this machine is secured to the lower end of the needle cylinder to rotate therewith and comprises a frame member 152 fixed to the usual ring' gear (not shown) in any convenient manner. This frame member is open ,atedbya i'gsewno at the sides and is provided with bearings for a air of rollers 1 gch is concave and the other convex.. The rollers are connected. at -one end by suitable aring to cause' them' to rotate together.

t the other end the roller 153 is rovided with a ar, 155 meshing wit a gear 156 which in turn is driven y a gear on the same shaft with a ratchet' 157 orintegral with the ratchet. The ratchet is operawl 158 on a pawl lever 159 and is held in a'ustable position by means of a pair of aw 160 set so as to have their points spaced y one half the distance between two teeth of the ratchet so as to reduce backlash.-

A spring 161 normally holds the lever against a stop 162 on the downwardly projecting part of the take-up frame and the spring is attached at one end to an adjusting screw 163 through an ov ing in a bent arm of a dependin bra et 164, said screw carrying a. nut 1 by which the tension of the spring ma be adjusted.` e he lever ,159 has a downwardly projecting arm 166 positioned to engage with an abutment 167 (Fi 10 and 12) at each rotation of the need e c linder when the parts are in the position in icated in Fig. 12. The disc133 on the pattern drum has cams at 169 for lifting the lever 170 pivoted at 171. This lever has attached -thereto a'tits other end' a rod 172 ca 'ng the abutment 167 said rod being slidab y mounted in a guide 173. A

ring 174 attached at one end to a projection i174 tends to bring the abutment 167 into the position indicated in Fig. 12 which is the correct position for actuatmg-the take-up during round-and-round knitting. When the pouches such as heels and toes of stockings are be' formed the cam shaft 127 is turned so as to rin thecams 169 under the end 'of 1'. takeup rollers not opera lever 170 an pull the abutment 167 down below the position at which it can en age the pawl lever 159. The take-up there ore does not act on the fabric during the formation of pouches, i. e. during reciprocating knitting.

v -Operation v In "a, typical operation of the machine of my invention for knitting a stockin the needle cylinder revolves and the c nder needles are o rated to knit a loo eigs margin of plain abric. v At this time t e dial, of course, rotates with the cylinder but the dial cam capand related parts are in the circum'- ferential position illustrated in Fi that the needle wave'is in a position where the needles will not take yarn. yAfter a suits able length of material has been knitted the motion of the machine is changed to reciprocatiig` for knitting the toe pocket, an addition v arn being put into action as usual throu'g out the toe. It will be recalled 'that during the formation of thesgdpockets the 3 and 154, the first one of needle projecting the lever 170 at this time being lifted by one or the other of the cams 169 to bring the abutment 167 out of reach of the pawl e ver 159. lThe foot and heel are 'also made in usual manner and a short distance above the heel is formed as lain fabric. The incidental operations suc as change of stitch length, etc. up to this timev have been as in conventional manufac i knittingu ma- The knitting is now to be chan d froml ture of hosiery on a circular chine.

plain to ribbed for the production o a ribbed ieg.w As soon as'the ankle portion has been knitted the travel of the pattern chain is changed from the normal 1 x 4 to 1 x 1, i. e. instead of moving the chain one step to four revolutions of the cylinder it now is moved one step to each revolution of the' cylinder, and' a lug of the proper height on the ri ht hand side of the patternchain causes the ial cam to move from its idle position (Fig. 16) to the latch opening position Fig. 1-5) The needle latches are opened by a rush 57 (Fig. 15) While the dial needles will be projected to their most outward position at this time the needle wave of the dial needles is far enough circumferentially from the knitting position to prevent the dial needles from taking yarn. It may be noted' that all lugs on the pattern chain controlling the ositions of the dial cam are at the right-han side of the chain whereas the lu for controlling the other operations of tgz machine are at the left-hand side. The dial needles remain in this position for asman revolutions as are requiredlfor o ning the atches, the dial cam is then cause to rotatetoward the'knitting position (Fig. 13) and the cair track in plate 41 just above the -dial -cam whicli'iss'tationarycauses the dial needle projecting cam 62 to move to the half-way vposition (Fig. 14) The dial needles will\.now be in the firstposition and also to take `their first course of f yarn at the same time.

The positions of the follower 42 corresponding to the different phases of the knitlll 9ting operation and to the positions-of the cam shown in Figures 13K to 16 are illustrate ing cam is in idle position (Fig. 16) and the cam cap has been turned' to the limit of in Fig. 18. When the pin is in the position indicated at a the projecti its movement in a clockwise direction, viewed 0 from above.

the latchyure 15. T next-movement in the same When the camcap is i'iowl moved counterclockwise to move the follower from position a toposition b the parts assume Keningvposition illustrated in Fig-` e lll where the yarn will now be taken and held by the hooks of the needles.

After the dial needles have taken one course of yarn a lug of the properheight causes the 5 dial cam to rotate away'from the knitting osition, the projecting cam remaining in the alf-way position inorder to hold the loops of the first course, the follower being now in position c. This movement serves to prevent 9 the dial needles from taking any more yarn for the next one or more revolutions as may be required. These courses of plain knittin serve to close up the large holes that would otherwisebe made in the transfer.A The next stepin the operation is to turn the dial cam ca to hrjrng the cam 62 into the knitting position (F1 13), the follower now 'being at e. It should e noted thatthe idle position of the follower at ais at the same distance from the axis of the machine as are the positions c Similarly 'the follower and the cam are at the same distances from the axis in pgsitions b and e of the follower. It should remarked also that when the follower is in position 'c the needles are in tucking osition ut cannottake yarn because the nee le wave has not been moved sufficiently far about the machine in a counterclockwise direction whereas when it has been advanced far enough tobrin 4the follower to position d yarn will be ta en. In moving in the contrary direction from e to lc loops already on the needles will beheld in either position d or position c of the follower. Finally position b is both the latch-opening position and the casting-off position so far as the follower and the needle projecting cam are concerned. It is to be understood that while making the transfer the pattern chain was traveling one step to each revolution of the c linder and when the transfer is completed t e travel of the attern chain is chan ed back to one step 3f t e chain to four revolutions of the cylin- It is desirable tovgi e the stockin a finish by making what are ca led welts. ese may be made in the following manner. First the travel of the pattern chain is chan ed from -1 x 4 to 1 x 1. Alug of the proper eight on this pattern chain'causes the dial cam cap to rotate away from the knitting position causthe rojectin cam to move to the halfway position (F1g. 14), the follower being at d. The dial, needles will still receive yarn lbut the old loops will not knit olf. l The dial cam may be held in this position* for as many courses as isvwanted, after which it moves to c, the position of the cam remaining as be fore, but the dial needles ceasing to take yarn. Plain courses are now knitted as far as necessary according to' the'style of welt desired.. The dial cam is then caused to rotate back to the knitting position thereby allowing the oldloops to be knitted o. As many of these welts can be made as required.

After the welts have been made the dial cam is caused to rotate away from the knitting position and to the cast-ofposition which is the same as the latch-opening When the loops have been cast off m the dial needles the dialcam is rotated still further away from the knitting osition to its idle position. The travel o the pattern chain is now changed from 1 x 1 to 1 x 4. The machine is now ready to begin a new stock- 1n t will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit m self to what is shown in the drawings described in the specification but only as indicated in the appended claims.

Figure illustrates one such chan e. The yarn pusher 149 is pivpted on a brac et 150 similar to that shown in F res 18 and 19, the yarn pusher, however, ing smaller in form than' that in the other figures. Whereas the yarn pusher 149 is nearly S-shaped, that of Fi 20 approaches more nearly to a straig t line, the upper leg bein approximately in line with the notched ower end. This form is preferable in some instances as being of smaller construction and less liable to get out of order.
